英文摘要	系统研究了热解和氧化条件对聚碳硅烷氮化热解法制备SInO陶瓷的影响.研究发现,氮化脱碳反应主要发生在800℃之前,且脱碳彻底,碳质量分数低于1%;在氮气气氛下继续烧成,最终生成陶瓷的氮质量分数可达35.65%.氮化前对聚碳硅烷进行氧化交联可提高陶瓷产率至61.84%,但是产物中氮质量分数显著降低到20%以下,产物为无定型态的SInO陶瓷.; SiNO ceramic has very excellent comprehensive properties and is one of the best candidates for ceramic matrix composites.In this work,influences of pyrolysis and curing conditions on the SiNO ceramic prepared with pyrolysis nitridation are systematically studied.The results show that decarbonization is completed before 800 ℃ with carbon residue lower than 1%(by mass).After pyrolysis in N2,nitrogen content is as high as 35.65%(by mass).Oxidation curing before ammonolysis can improve ceramic yield.The ceramic yield is 61.84%(by mass)but the nitrogen content decreases significantly(below 20%)by mass,and the product is amorphous SiNO ceramic.Therefore,high-yield and low-carbon-content SiNO ceramic can be prepared with pyrolysis nitridation of polycarbosilane.; 国家自然科学基金(51002127)
